Pic of the Day

Thunderstorms almost spoiled this view of the spectacular 2011 June 15 total lunar eclipse. Instead, storm clouds parted for 10 minutes during the total eclipse phase and lightning bolts contributed to the dramatic sky.

Captured with a 30-second exposure the scene also inspired one of the more memorable titles…The lightning reference clearly makes sense, and the shadow play of the dark lunar eclipse was widely viewed across planet Earth in Europe, Africa, Asia, and Australia. The picture itself, however, was shot from the Greek island of Ikaria at Pezi. That area is known as “the planet of the goats” because of the rough terrain and strange looking rocks.

Political Correctness Bastion of Anti-Science Republicans

❝ Staff at the US Department of Agriculture (USDA) have been told to avoid using the term climate change in their work, with the officials instructed to reference “weather extremes” instead.

❝ A series of emails obtained by the Guardian between staff at the Natural Resources Conservation Service (NRCS), a USDA unit that oversees farmers’ land conservation, show that the incoming Trump administration has had a stark impact on the language used by some federal employees around climate change.

❝ A missive from Bianca Moebius-Clune, director of soil health, lists terms that should be avoided by staff and those that should replace them. “Climate change” is in the “avoid” category, to be replaced by “weather extremes”. Instead of “climate change adaption”, staff are asked to use “resilience to weather extremes”.

RTFA for details of sophistry required by Trumpkins appointed to implement corporate obedience.

Back when conservatives and other self-righteous hacks introduced political correctness to US Government, neither party had a problem with stationing our military in 150 foreign countries managed by the shiny new “Department of Defense” instead of the War Department that actually was premised upon defending the continental United States.

Let’s hope for more backbone in a changing generation of Democrats.

Amphibious robot with undulating propulsion


Click to website with video demo

The US Office of Naval Research…is funding an amphibious optionally autonomous underwater vehicle (AUV) or remotely operated vehicle (ROV) prototype for use in littoral, surf and tide-zones, high-vegetation, debris-filled, or icy environments. The prototype was showcased and demonstrated at the Naval Future Force Science and Technology Exposition in Washington, DC, in July…

Pliant Energy Systems’ agile swimmer robot uses multi-stable non-linear systems to produce repetitive undulating motion for propulsion. Instead of propellers, the planar hyperbolic geometry and flexible electroactive-polymer undulating fins are able to propel the system underwater, on sandy beaches, over sea- or land-based vegetation, slippery or wet rocks, and over or under ice floes and ice shelves. It is powered by a lithium-ion battery.

Can’t wait to see what this critter might do untethered.
